Abstract: In this paper, we prove Lusztig's conjecture for $ G^F = SL_n(\mathbf F_q)$, i.e., we show that characteristic functions of character sheaves of $ G^F$ coincide with almost characters of $ G^F$ up to scalar constants, assuming that the characteristic of $ \mathbf F_q$ is not too small. We determine these scalars explicitly. Our result gives a method of computing irreducible characters of $ G^F$.
